Can't deal any damage to mole boss

[geemuboi]

I have tried 2 playthroughs, but the result was the same.

Hi geemuboi,

I'm really sorry this is happening, I'm not sure why!
I have a couple of questions:

1) Are you able to deal damage to the other enemies in the game?

2) What spec computer are you running?

A chap at my work has the same issue.
I will see what PC he is using. I'm wondering if it's a frame rate + physics problem.

Again I'm sorry this is spoiling your experience and will get to the bottom of it.

Thank you for the video.
Gaz

Thank you for the quick reply!

1) Yes, I am. I have defeated snails/wasps/moles along the way to boss.

2) OS Windows 7
CPU Intel Core i7-4470
RAM 8 GB
Video Card GeForce GTX 1050Ti

Thanks very much. I had an idea of why this is happening, but it's a best guess. I will do a fix and if you can accept my Steam friend request then I'll get you access to my test branch which will have the fix :-)

Thank you for your patience

Hello! I have pushed my fix live. Please let me know if it now works for you.

Many thanks,
Gaz

I have tried 2 playthroughs (with/without 4th heart) in current state, but boss was still invincible...
Also game progress haven't been saving since I've started playing.

I was finally able to defeat big mole and saved grandpa!

Game progress can be saved only when game is shutting down, and I can defeat mole boss only when resuming save data.

Mole boss will be invincible by a playthrough in one sitting.

Ah thank you for the feedback! I'm still unsure why it is happening! I'm glad you were able to work around it though. I'll have to have another think as to why this is occurring
